Parameters: < time> is the forward delay time in seconds , the valid range is 4 to 30.
Command mode: Global Mode
Default: The default forward delay time is 15 seconds.
Usage Guide: When the network topology changes, the delay time for a port changes from blocking status to listening status. This is called forward delay time. The forward delay time, Hello time and max age time are associated. When configuring MSTP time parameters, the following conditions must be met, otherwise the MSTP may not work properly:
2×(Bridge_Forward_Delay – 1.0 seconds) >= Bridge_Max_Age Bridge_Max_Age >= 2 ×(Bridge_Hello_Time + 1.0 seconds)
Example: Setting MSTP forward delay time to 20 seconds in Global Mode.
